Comparison of the cometary fireball EN310317_023002 (left) and the asteroidal fireball EN181017_231532 (right). Both meteoroids were on cometary-type orbits with (a, e, i) = (3.01,0.68,23°) and (3.04, 0.71, 49°), respectively. The cometary fireball appeared at heights of 98–61 km and reached a maximum absolute magnitude of −13.2. The meteoroid photometric mass was 6.7 kg. The asteroidal meteoroid was much smaller (0.04 kg) and the fireball was fainter (−7.7 mag) but longer (89–37 km). The slopes of the trajectories were almost identical (28^° and 29^°, respectively, to the vertical).
